19-year-old action movie stuntwoman Choko
and her sister have come to Hollywood,
now named New Yokohama,
to audition for a part in a new film.
Assassinated on arrival by mysterious agents,
Choko's body is buried
in the wilderness on the outskirts of New Yokohama,
and her sister is nowhere to be found.
An unknown amount of time passes,
and air fills Choko's lungs once more
as she rises from the soil.
By some miracle, she's still alive,
but something about this world is very wrong.
Zombies roam the streets,
monsters and a few remaining humans
compete for scarce resources.
Criminal underworlds are at war with each other
while a mysterious organization fights back
to rebuild social order.
Recovering a vehicle from a movie studio ruins,
Choko embarks on a journey across the United States
to find her sister.
But what lays in wait for her on the way?
What has unfolded during Choko's slumber?
